SPOOL OR BOBBIN.

SPECIFICATION forming part of Letters Patent No. 366,415, dated July 12, 1887.

Application filed March 11, 1887. Serial No. 230.491. (No model.)

'Massachusetts, have invented certain new and useful Improvements in Spools or Bobbins; and I do hereby declare the following to be a full, clear, and exact description of my invention.

Heretofore spools have been made of wood, and after being in use some time the heads are liable to become detached from the barrel of the spool or to check or crack, and in winding thethread gets into the cracks in the heads and breaks and causes more or less inconvenience. Spools or bobbins have also been made of metal or a combination of wood and metal, but have not proved satisfactory.

My invention consists of plain spring-steel head or heads, with or without a flange, fast ened to a wooden barrel, and a plug of sufficient width to get friction enough to turn the spool or bobbin when in use. The plug is fastened to the inside of the barrel with glue or cement, or by a pin or pins passing through the side of the barrel and into the plug, as there are times when the spool is used where there is dampness or moisture.

The spring-steel-head is firmly fastened to the barrel by one or more pins,passing through the plug, the spring-steel head, and into the wooden barrel a suffieient distance.

I am aware that corrugated flanged heads have been used and patented, but find by actual use that there is not enough stiffness to the corrugation to withstand the use to which it is put, but after being used a short time, by dropping or hitting each other, the heads become bent, so that it is impossible to wind the thread on them.

In my spool I make the head or heads of plain springsteel, of a sufficient degree of elasticity,or, as it is called, spring, so that when spools are dropped or thrown against each other the steel heads will spring and return to their proper position when the pressure is removed, and will not bend.

In the accompanying drawings, forming part of this specification, Figure 1 represents the spool or bobbin complete, with one end bisected, showing the construction; B B, the head or heads; B, the flange on the head B; O, the plug; E E, the pin-holes through which the pins are driven for holding theheads firmly in position; F, the hole in the center of the plug 0; H H, the pin-holes in the barrel A and plug 0, for driving the pins for holding the plug Gin the barrel A; A, the wooden barrel, and G- the hole in the barrel A, into which the plug 0 is driven.

Fig. 2 represents a side and end viewof the barrel A; G, the hole in the center of the barrel A; E E, the holes in the barrel A, into which the pins 0 O are firmly driven, and H H the pin-holes.

Fig. 3 represents the face and edge of the plain springsteel head B; B, the flange; H, the hole through the center, of the same size as the hole G in the barrel A, Fig. 2, and E E the pin-holes.

Fig. 4 represents the plug 0; F, the hole through the center; E E, the pinholes, and H H pin holes to match pin-holes H H in barrel A.

Fig. 5 represents a side and end view of the pins D D.

Having fully described my invention, what I desire to secure Letters Patent on is- As a new article of manufacture, a spool or bobbin having spring-steelheads and a wooden barrel, and having said heads held in position by pins and plugs, as shown and described.
